Control thruster

Control thrusters in use aboard Deep Space 9.

Control thrusters are parts of the propulsion technology aboard a space station.

Fun Fact:

• After the Cardassian withdrawal from Bajor in 2369, Deep Space 9 had only six working control thrusters.
  Moving the station with those six remaining thrusters would have taken about two months.
  Instead, the station's deflector generators were modified to create a subspace field around the station, lowering its inertial mass.
